PSES v3.4.0 is the first version bundled since the last stable. I'll go from there and see if I can identify the change which caused this.

Bisected, first bad release seems to be v2022.5.2-preview. (@kborowinski where were you for the previews?! 😜)

[kborowinski]

@andschwa Sorry 😅, didn't want to ruin your day. In my defense - I can't use preview versions of VSC or extensions at work. So there you have it 😋

[andyleejordan]

So, good news first, narrowed it down to PowerShell/PowerShellEditorServices#1799. Reverted that on top of master and everything was back to normal. Bad news: that's a big PR and we definitely want the functionality in it, so now we got some troubleshooting to do.

Ok, we found and fixed it. Thanks for the report!

@kborowinski within a few minutes you should be able to update to https://github.com/PowerShell/vscode-powershell/releases/tag/v2022.6.2-preview and this should be resolved!

@andschwa Thanks! It works like a charm!
